The device (12) has an inductor (20), a parallel capacitor (24) and a switching element (26) varying from a component of a heating frequency unit (30). The switching element switches the parallel capacitor in an operation mode, and is supported parallel to the inductor that is switched between a main resonance unit (40) and the heating frequency unit. The switching element switches another inductor (22) parallel to the former inductor in the operating mode. The switching element switches both the parallel capacitor and former inductor parallel to the latter inductor. Independent claims are also included for the following: (1) a domestic appliance (2) a method for operating a domestic appliance induction heating device.
